Over the past few decades, most of research has been conducted on the extraction method, composition and cell surface characteristics connected with EPS. It was recently proposed that activated sludge floes are comprised of different types of EPS with distinct metal ion binding characteristics. Fe (III) was a common wastewater composition, in practice, which may promote the biofilm activity and amount...
A pilot-scale hybrid coagulation/membrane bioreactor (HCMBR) was investigated for real textile dyeing wastewater advanced treatment. Poly-aluminum chloride (PACI) was selected and used in the experiments. The HCMBR performed well in the removal of organic matter and total phosphate (TP). As compared to membrane bioreactor (MBR), HCMBR achieved much higher removal efficiencies in CODcr, UV254 and TP,...
The effect of shear stress on the EPS secretion was investigated in a suspended carrier biofilm reactor. A sudden increase of shear stress on the biofilm enhanced the EPS- polysaccharides secretion after an acclimation period. However, as the biofilm's structure reestablished and reached a steady state again, the EPS-polysaccharides secretion dropped down and stayed at a value which approximated to...
